WASHINGTON (AP) — White House press secretary Sarah Sanders has been interviewed as part of special counsel Robert Mueller’s Russia investigation.

Sanders says in a statement released Friday that she was "happy to voluntarily" sit for the interview. It was unclear when Sanders was interviewed but she says her boss, President Donald Trump, urged her to "fully cooperate."

Mueller is believed to be close to wrapping up his investigation into possible collusion between Trump’s presidential campaign and the Russian government. Trump has denied collusion and has denounced the investigation as a political “witch hunt.” Sanders has also used the “witch hunt” language to describe Mueller’s inquiry.
